OxygenOS 3.5.4 is now rolling out to a OnePlus 3T near you, and it's still based on Android 6.0.1 Marshmallow unfortunately. If you were craving a taste of Nougat, you'll have to wait some more, but probably not a lot more, since the Chinese company promised that the Android 7.0 update would hit by the end of this month.

Going back to today's release, this comes with optimizations for T-Mobile US, reduced lag when the battery is under 5%, better Bluetooth connectivity for Mazda cars, and increased overall system stability. GPS and orientation preferences will be restored once you go out of battery saving mode, and a flashlight usability issue has been fixed in WhatsApp. Additionally, "various bug fixes" have been implemented.

The update is rolling out over-the-air in an incremental fashion, which means that it will only reach a small percentage of phones today. A broader rollout will commence "in a few days", according to OnePlus.

Bugs could could be encountered at any stage...doesn't mean Android released especially on the Pixels was half-baked. After the OEMs take all the damn time in the world to test and test...most times adding useless stuff, what do we still get? Bugs!
